Updated U-value Regulations – June 22

This new release will explain the recent changes to building regulations, targeting U-value increases in particular.

Why are the U-value regulations changing?

The lower the u-value, ultimately more insulation is required to meet the same target. As a result, there will be less requirement for heat and power in homes.

In the UK, currently 40% of total energy use comes from heating and powering for buildings. Lower U-values will mean warmer homes, resulting in less demand for energy. In addition, this means cost savings for homeowners.

As part of the Department Business, Energy & Industrial Strategy, they are aiming to half all energy usage by 2030. Their mission for this can be found at the following link – Click Here!

When are the improved U-values being rolled out?

The Amendment Regulations and accompanying Approved Documents L: Volumes 1 and 2 came into force on 15 June 2022.

These changes however will not apply should the plans be deposited to a local authority before this date, and started prior to 15 June 2023.
